Hi All,
My u-boot is u-boot-1.1.4,and the version of kernel is 2.6.10.Both of
them can boot from NAND Flash normally,but there are some messages that
puzzle me when my kernel boot from NAND Flash.The messages are as follows:
DaVinci NAND Controller rev. 2.1
No NAND device found!!!
Chip Select is not set for NAND
The process of booting is like that:
